| titleOfInvention | Manufacturing method of polarizing film and manufacturing apparatus of polarizing film |
| abstract | The present invention provides a method for producing a polarizing film and an apparatus for producing a polarizing film capable of producing a polarizing film having good optical performance. A method for producing a polarizing film for producing a polarizing film from a polyvinyl alcohol-based resin film includes the steps of treating the polyvinyl alcohol-based resin film with a dyeing treatment liquid containing iodine; adding a crosslinking agent and an iodide salt to a liquid containing a crosslinking agent and an iodide salt The step of obtaining the first cross-linking treatment liquid in water with an oxygen dissolved amount of 2.0 mg/L or less; and the polyethylene after the step of treating with the dyeing treatment liquid in the cross-linking treatment liquid containing the first cross-linking treatment liquid The process of impregnating the alcohol-based resin film. |
